GridControl raises an exception on expanding its detail grid in a separate UI threa

created 9 years ago

Hi guys,

I have an app that creates multiple UI threads. It has one master-detail DXGrid on the window. When I open two instances of the same window and click on the [+] sign to expend the detail level it blows up with the following exception and the call stack. Please see below.

I tried to search the support website but couldn't find anything that resembles this problem.

Can you please help me out

Thanks,

Leon

Exception thrown: 'System.Windows.Markup.XamlParseException' in PresentationFramework.dll

Additional information: The calling thread cannot access this object because a different thread owns it.
